はarrayadapterの代わりにbaseadpaterを使用してみてください。

public class Studentloader extends BaseAdapter implements OnClickListener{ 

    private Context slcntx; 
    private ArrayList<HashMap<String, String>> data = new ArrayList<HashMap<String, String>>(); 
    private static LayoutInflater inflater=null; 
    public ImageLoader imageLoader; 
    private String url; 

    public Studentloader() { 
     this.data = new ArrayList<HashMap<String, String>>(); 
    } 


    public Studentloader(Context ctx, ArrayList<HashMap<String, String>> d) { 
     slcntx = ctx; 
     data=d; 

     inflater = (LayoutInflater)slcntx. 
       getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     imageLoader = new ImageLoader(slcntx); 
    } 

    public int getCount() { 
     return data.size(); 
    } 

    public Object getItem(int position) { 
     return position; 
    } 

    public long getItemId(int position) { 
     return position; 
    } 

    public void clearData() { data.clear(); } 

    /********* Create a holder Class to contain inflated xml file elements *********/ 
    public static class ViewHolder{ 

     public TextView studentTV; 

     ImageView image; 

    } 

    public View getView(int position, View convertView, ViewGroup parent) { 

     View vi=convertView; 
     ViewHolder holder; 
     HashMap<String, String> pers = new HashMap<String, String>(); 

     pers = data.get(position); 

     if(convertView==null) { 

      /****** Inflate tabitem.xml file for each row (Defined below) *******/ 
      vi = inflater.inflate(R.layout.allfees, null); 

      /****** View Holder Object to contain tabitem.xml file elements ******/ 

      holder = new ViewHolder(); 
      holder.studentTV = (TextView) vi.findViewById(R.id.studentname); 


      holder.image = (ImageView) vi.findViewById(R.id.profileimage); 


      vi.setTag(holder); 
     } else holder=(ViewHolder)vi.getTag(); 

     /************ Set holder with LayoutInflater ************/ 
     holder.studentTV.setText(pers.get("studentsname")); 

     ImageView image = holder.image; 

     url = pers.get("urls");  //Using LazyImageLoader for loading images using URLs cz in my case I needed to upload student picture, so passed the url data in the arraylist and received it here. 
     System.out.println(url); 

     imageLoader.DisplayImage(url, image); 

     /******** Set Item Click Listner for LayoutInflater for each row ***********/ 
     //vi.setOnClickListener(new AdapterView.OnItemClickListener(position)); 
     return vi; 
    } 

    @Override 
    public void onClick(View arg0) { 
     // TODO Auto-generated method stub 

    } 

}
